DESCRIPTION OF EMBODIMENTS

To allow a person skilled in the art to better understand solutions of this application, the following describes technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. The described embodiments are merely some rather than all of the embodiments of this application. Other embodiments that can be obtained by a person of ordinary skill in the art based on the embodiments of this application shall fall within the protection scope of this application.

In the specification, claims, and accompanying drawings of this application, the terms “first,” “second,” and so on are intended to distinguish between similar objects rather than describe a specific order or sequence. It is to be understood that the data termed in this way are interchangeable in a proper case, so that the embodiments of this application described herein can be implemented in other orders than the orders illustrated or described herein. Moreover, the terms “include”, “have” and any other variants mean to cover the non-exclusive inclusion, for example, a process, method, system, product, or device that includes a list of steps or units is not necessarily limited to those expressly listed steps or units, but may include other steps or units not expressly listed or inherent to such a process, method, product, or device.

According to an aspect of the embodiments of this application, an interactive control method is provided. Optionally, in an implementation, the foregoing interactive control method may be applied to, but is not limited to, an environment shown in FIG. 1. A user 102 may perform a touch operation on a touch panel 104, and a host 106 recognizes the touch operation after obtaining the touch operation received by the touch panel 104, and generates an interaction request according to a recognition result. The host 106 controls, according to the interaction request, a holographic projection-based virtual role (or character) 110 projected by a projector 108 to perform an interactive action matching the interaction request. In this device, a battery 112 is configured to power the whole device.

FIG. 1 is merely an example of a hardware structure, and does not constitute a limitation on this embodiment. The touch panel 104 and the projector 108 may exist separately. In this case, the touch panel 104 transmits a touch signal to the host 106 by using a signal transmission device connected to the touch panel 104. The projector 108 receives a to-be-projected interactive action from the host 106 by using a signal receiving apparatus.

In the related art, in a case that a holographic projection-based virtual role is displayed by using a holographic projection device, a client or a speech instruction are usually used for interacting with the holographic projection device. However, the foregoing method for interacting with the holographic projection device has monotonous control instructions, and the holographic projection device can only make simple responses. However, in this embodiment, a touch operation is obtained by using a touch panel, the touch operation is recognized, an interaction request is generated according to the recognized touch operation, and an interactive action matching the interaction request is performed according to the interaction request. In the foregoing method, a holographic projection device can be directly controlled by using a touch operation received by a touch panel, thereby providing varied instructions for controlling the holographic projection device, and improving the flexibility of the interaction with a holographic projection-based virtual role.

For convenience of understanding and explaining the interactive control method provided in this embodiment of this application, the description is made with reference to FIG. 2 below. The interactive control method provided in this embodiment of this application may be applied to a holographic projection device, and in an optional implementation, the interactive control method may include the following steps.

In step S202, a holographic projection device recognizes a touch operation performed on a touch panel. The holographic projection device is configured to display a holographic projection-based virtual role. Further, the touch panel is disposed on the holographic projection device.

In step S204, the holographic projection device generates an interaction request according to the recognized touch operation. The interaction request is used for requesting interaction with the holographic projection-based virtual role.

In step S206, the holographic projection device controls the holographic projection-based virtual role to perform an interactive action matching the interaction request.

For example, the foregoing interactive control method may be applied to, but is not limited to, a process of interacting with the holographic projection-based virtual role in the holographic projection device. For example, the foregoing interactive control method may be applied to a process of interacting with a projected holographic virtual cartoon character, and may also be applied to a process of interacting with a projected holographic virtual building.

For convenience of understanding and description, an example in which the interactive control method is applied to the process of interacting with a holographic virtual cartoon character projected by the holographic projection device is used for description. In a case that the holographic virtual cartoon character is projected by the holographic projection device, a user may observe the holographic virtual cartoon character. In this case, after the user touches the touch panel to generate a touch operation, the holographic projection device recognizes the touch operation, generates an interaction request, and controls the holographic virtual cartoon character according to the interaction request to perform an interactive action, such as to become shy, matching the interaction request. In this case, the user may see that the holographic virtual cartoon character performs the interactive action, thereby completing the interaction between the user and the holographic virtual cartoon character.

In this embodiment, a holographic projection device uses a control method in which a touch operation is first obtained by using a touch panel, so that the touch operation is recognized, and an interaction request is then generated according to the recognized touch operation, so that an interactive action matching the interaction request is performed according to the interaction request. In the control method, the holographic projection device can be directly controlled by using a touch operation received by a touch panel, thereby providing varied instructions for controlling the holographic projection device, and improving the flexibility of the interaction with a holographic projection-based virtual role.

For example, the interactive action may include, but is not limited to, a body movement of the holographic projection-based virtual role and/or a voice of the holographic projection-based virtual role. For example, the “controlling the holographic projection-based virtual role to perform an interactive action matching the interaction request” may be: controlling the holographic projection-based virtual role to play an animation matching the interaction request; and/or, controlling the holographic projection-based virtual role to play audio matching the interaction request.

The controlling the holographic projection-based virtual role to play audio may include, but is not limited to, controlling the mouth of the holographic projection-based virtual role to change and simultaneously playing the audio by using a sound playing apparatus.

The touch operation may be obtained by using touch information generated by the interaction between a touch point and the touch panel. After the touch information is obtained, the touch operation is recognized according to the touch information.

The touch information may include, but is not limited to, at least one of the following: touch action duration of the touch point, a touch trajectory of the touch point, and a touch position of the touch point.

The touch point may include, but is not limited to, a touch position between a human body or a tool used by a human body and the touch panel. The human body may include, but is not limited to, any part such as a finger, a palm, the back of a hand, a nail, the forehead, the chin or a cheek of a human. The touch point may include, but is not limited to, a plurality of touch points. For example, in a case that the palm touches the touch panel, a plurality of touch points is formed. The plurality of touch points is synchronized and acts accordingly. In a case that the finger touches a touch screen, a touch point is formed. The touch information may include, but is not limited to, movement information of the touch point or time information of the touch point. For example, an example in which the touch point is a touch position between the finger and the touch screen is used for description. The finger may move in a process of touching the touch panel to leave a trajectory on the touch screen; or the finger touches the touch screen a single time and leaves in a short time, so that a click operation is performed on the touch screen. In this way, the trajectory or the click operation may be used as the touch information, to recognize the touch operation according to the touch information.

Optionally, the recognizing, by the holographic projection device, the touch operation according to the touch information includes:

(1) determining, by the holographic projection device, that the touch operation is a caress performed on the holographic projection-based virtual role in a case that the touch information indicates that a quantity of swipes performed on the touch panel by the touch point is greater than a first threshold, an action in which a movement distance of the touch point on the touch panel is greater than a second threshold being recognized as the swipe; and

(2) in a case that the touch information indicates that the movement distance of the touch point on the touch panel is less than a third threshold and action duration of the touch point on the touch panel is less than a fourth threshold, the holographic projection device determines that the touch operation is a pat performed on the holographic projection-based virtual role.

The first threshold, second threshold, third threshold, and fourth threshold may be set according to empirical values, but are not limited thereto. For example, the touch point is formed through the touch between the finger and the touch panel. As shown in FIG. 3, after the finger touches the touch panel and forms a touch point A, the finger moves from the touch point A to a touch point B, a movement distance being a. A relationship between a and the first threshold is determined, and in a case that a is greater than or equal to the second threshold, it indicates that a current operation is a swipe. In a case that a is less than the third threshold, it indicates that the current operation is not a swipe, and other conditions are required for determination. Optionally, the action duration may include, but is not limited to, duration of existence of the touch point a single time. For example, the finger touches the touch panel for one second, so the action duration is one second.

Further, in a case that it is determined that the current operation is a swipe, in a case that a plurality of swipes is received, a quantity of received swipes is determined. In a case that the quantity of swipes is greater than the first threshold, the holographic projection device may calculate to determine that the user performs the plurality of swipes on the touch panel. In this case, the holographic projection device may determine that the user is performing a caress. In a case that the current operation is not a swipe, and the action duration of the current operation is less than the fourth threshold, the holographic projection device may calculate to determine that the user performs a single short-time touch operation on the touch panel. In this case, the holographic projection device may determine that the user is performing a pat.

The determining, by holographic projection device, that the touch operation is the caress performed on the holographic projection-based virtual role may include, but is not limited to, the following methods: obtaining, by the holographic projection device, a first position at which the touch point stays on the touch panel at a first moment and a second position at which the touch point stays on the touch panel at a second moment, a time interval between the first moment and the second moment being a frame period; recognizing, by the holographic projection device in a case that a distance between the first position and the second position is greater than the second threshold, an action in which the touch point moves from the first position to the second position as the swipe, and adding one to the quantity of swipes; and determining, by the holographic projection device in a case that the quantity of swipes is greater than the first threshold, that the touch operation is the caress performed on the holographic projection-based virtual role.

The method may include, but is not limited to, adding coordinate information to the touch screen. For example, FIG. 4 shows an optional touch node of the touch screen. A plane rectangular coordinate system is set with the lower left corner of the touch screen as the origin and the touch screen as the plane. Any point on the touch screen can obtain a coordinate value. For example, the coordinates of a point C are (x, y), x and y being positive numbers.

An exemplary description of a case that the palm touches the touch screen is provided with reference to FIG. 5. In a case that it is determined that the touch panel is in a to-be-detected state (S502), the palm touches the touch panel. It is determined by S504 whether a quantity of touch points is greater than 3, and in a case that the quantity of touch points is greater than 3, the coordinates of the touch points are recorded by S506. In this case, the coordinates of one of the touch points may be chosen, or the coordinates of all the touch points may be recorded. In a case that the touch points disappear, it is determined by S508 whether a quantity of the touch points is greater than 3 before the touch points disappear, and in a case that the quantity of the touch points is greater than 3, the disappearance coordinates of the touch points are recorded by S510. In this case, a touch point whose start coordinates are recorded may be chosen and the disappearance coordinates of the touch point are recorded, or the disappearance coordinates of all the touch points may be recorded. The start coordinates and disappearance coordinates of each touch point correspond to each other. A distance D between the start coordinates and the disappearance coordinates of a touch point is calculated by S512, and it is determined by S514 whether D is greater than the second threshold. In a case that D is greater than the second threshold, 1 is added to a quantity E of swipes by S516. It is determined by S518 whether E is greater than the first threshold, and in a case that E is greater than the first threshold, it is determined that a currently performed action is a caress. In this process, in a case that the quantity of the touch points in S504 and S508 is not greater than 3 or after it is determined that the current action is a caress, S522 is performed, and E is reset to 0. In a case of determining whether the quantity of the touch points is greater than 3, 3 may be set flexibly. In addition, the foregoing process is a process of determining whether the palm is performing a caress. In a case of determining whether the finger (or other parts) is performing a caress, the method may include, but is not limited to, deleting steps of S504 and S508 in the process in FIG. 5, and it is not necessary to determine whether the quantity of the touch points is greater than 3. It may be determined whether a current operation is the caress by using the remaining steps in FIG. 5.

The determining, by holographic projection device, that the touch operation is the pat performed on the holographic projection-based virtual role may include, but is not limited to, the following methods: obtaining, by the holographic projection device, a third position at which the touch point stays on the touch panel at a third moment and a fourth position at which the touch point stays on the touch panel at a fourth moment; and determining, by the holographic projection device in a case that a distance between the third position and the fourth position is less than the third threshold and a time interval between the third moment and the fourth moment is less than the fourth threshold, that the touch operation is the pat performed on the holographic projection-based virtual role.

For example, the description is provided below with reference to FIG. 6. For example, the touch operation is an operation performed on the touch panel by the palm. In a case that it is determined that the touch panel is in a to-be-detected state (S602), after the palm touches the touch panel, it is determined by S604 whether the quantity of the touch points is greater than 3, and in a case that the quantity of the touch points is greater than 3, the coordinates and generation moment of one touch point or all the touch points are recorded by S606. It is determined by S608 whether the quantity of the touch points is equal to 0, and in a case that the quantity of the touch points is equal to 0, the disappearance coordinates and disappearance moment of the one touch point or all the touch points are recorded, and a distance L between the coordinates of the touch point (e.g., a distance between the start coordinates and the disappearance coordinates of the touch point), and a time interval T between a generation moment and a disappearance moment of the touch point is calculated by S610. It is determined by S612 whether L is less than the third threshold, and it is determined by S614 whether T is less than the fourth threshold. In a case that L is less than the third threshold and T is less than the fourth threshold, it is determined by S616 that the current operation is a pat. In a case that L is greater than or equal to the third threshold, or T is greater than or equal to the fourth threshold, or it is determined that the current operation is a pat, the touch panel enters the to-be-detected state in S602 again. In addition, in a case that the touch point does not disappear, the position of the touch point and a current moment are periodically recorded.

After the recognizing, by the holographic projection device, the touch operation according to the touch information, the method further includes: obtaining, by the holographic projection device, an action region of the interaction between the touch point and the touch panel; and determining, by the holographic projection device according to a position of the action region on the touch panel, interactive information requested by the interaction request.

For example, as shown in FIG. 7, the touch panel is divided into six regions, A, B, C, D, E, and F, and the interaction generated in different regions correspond to different interactive information.

After the touch panel is divided into different regions, the sizes and shapes of the regions may be the same or different, and a quantity of the divided regions may be any positive number greater than or equal to 1.

For example, the determining, by the holographic projection device according to a position of the action region on the touch panel, interactive information requested by the interaction request includes either or both of the following two steps:

(1) The holographic projection device determines, according to the position of the action region on the touch panel, a role part of the interaction with the holographic projection-based virtual role; and determines, according to the role part, the interactive information requested by the interaction request.

The method may include, but is not limited to, dividing the touch panel into different regions, and different regions represent different role parts. For example, as shown in FIG. 8, the touch panel is divided into six parts, and the parts respectively correspond to the head, the left arm, the right arm, the stomach, the left leg, and the right leg. Touching different regions indicates interacting with different body parts of the role, for example, patting the head or caressing the stomach.

(2) The holographic projection device determines, according to the position of the action region on the touch panel, an interaction type of the interaction with the holographic projection-based virtual role; and determines, according to the interaction type, the interactive information requested by the interaction request.

The interaction type may include, but is not limited to, an interaction form or an interaction mode. The interaction form may include, but is not limited to, an action performed by the role or a played sound, and the interaction mode may include, but is not limited to, a current mode of the role.

The mode may include, but is not limited to, a plurality of modes of imitating human emotions, for example, a shy mode, an upset mode, a scared mode, and a cute mode.

For example, in FIG. 9, different positions of the touch panel are set to perform different interaction forms (for example, dancing or singing). Moreover, in FIG. 10, different positions of the touch panel are set as different modes of imitating human emotions, such as a shy mode and a cute mode).

For example, the interactive control method further includes: adjusting, by the holographic projection device, a mood parameter of the holographic projection-based virtual role; and controlling, by the holographic projection device, a role response mode of the holographic projection-based virtual role in a case that it is determined that the mood parameter reaches a target value, and/or, enabling, by the holographic projection device, a hidden skill of the holographic projection-based virtual role in a virtual scene.

In this embodiment of this application, an execution time of the adjusting, by the holographic projection device, a mood parameter of the holographic projection-based virtual role is not limited, which, for example, may be performed when controlling the holographic projection-based virtual role to perform an interactive action matching the interaction request.

The mood parameter may be indicated by using a number or in a form such as a quantity of red hearts or an energy value. The hidden skill may include, but is not limited to, a new animation, a new sound or a new phase. For example, the hidden skill is a new animation. After the mood parameter reaches a particular value, the role may be allowed to play the new animation. In a case that the mood parameter does not reach a particular value, the role is not allowed to play the new animation.

According to this embodiment, a holographic projection device performs a method in which a touch operation is obtained by using a touch panel, so that the touch operation is recognized, an interaction request is generated according to the recognized touch operation, and an interactive action matching the interaction request is performed according to the interaction request. In the foregoing method, the holographic projection device can be directly controlled by using a touch operation received by a touch panel, thereby providing varied instructions for controlling the holographic projection device, and improving the flexibility of the interaction with a holographic projection-based virtual role.

Based on the scenario content described above, different implementations of the interactive control method provided in this embodiment of this application are described below in detail with reference to the scenario content.

In an exemplary implementation, the recognizing, by the holographic projection device, the touch operation performed on the touch panel disposed on the holographic projection device includes the following steps.

In a first step, the holographic projection device obtains the touch information generated by the interaction between the touch point corresponding to the touch operation and the touch panel.

In a second step, the holographic projection device recognizes the touch operation according to the touch information.

For example, the finger interacts with the touch panel. After the finger interacts with the touch panel, the position of the touch is the touch point. In a case that the finger moves, the touch point may move accordingly. A movement trajectory of the touch point, touch action duration of the finger, and the position of the touch point are obtained and used as the touch information. The touch operation is recognized according to the touch information.

According to this embodiment, the touch information generated by the interaction between the touch point corresponding to the touch operation and the touch panel is obtained, and the touch operation is recognized according to the touch information, thereby improving the flexibility of controlling the holographic projection device.

In an exemplary implementation, the recognizing, by the holographic projection device, the touch operation according to the touch information includes the following steps:

In a first step, the holographic projection device determines, in a case that it is determined according to the touch information that a quantity of swipes performed on the touch panel by the touch point is greater than a first threshold, that the touch operation is a caress performed on the holographic projection-based virtual role, the swipe being an action in which a movement distance of the touch point on the touch panel is greater than a second threshold.

In a second step, the holographic projection device determines, in a case that it is determined according to the touch information that the movement distance of the touch point on the touch panel is less than a third threshold and action duration of the touch point on the touch panel is less than a fourth threshold, that the touch operation is a pat performed on the holographic projection-based virtual role.

The first threshold, second threshold, third threshold, and fourth threshold may be set according to empirical values, but are not limited thereto. For example, the touch point is formed through the touch between the finger and the touch panel. As shown in FIG. 3, after the finger touches the touch panel and forms a touch point A, the finger moves from the touch point A to a touch point B, a movement distance being a. A relationship between a and the first threshold is determined, and in a case that a is greater than or equal to the second threshold, it indicates that the current operation is a swipe. In a case that a is less than the third threshold, it indicates that the current operation is not a swipe, and other conditions are required for determination. Optionally, the action duration may include, but is not limited to, duration of existence of the touch point a single time. For example, the finger touches the touch panel for one second, so the action duration is one second.

Further, in a case that it is determined that the current operation is a swipe, in a case that a plurality of swipes is received, a quantity of received swipes is determined. In a case that the quantity of swipes is greater than the first threshold, the holographic projection device may calculate to determine that the user performs the plurality of swipes on the touch panel. In this case, the holographic projection device may determine that the user is performing a caress. In a case that the current operation is not a swipe, and the action duration of the current operation is less than the fourth threshold, the holographic projection device may calculate to determine that the user performs a single short-time touch operation on the touch panel. In this case, the holographic projection device may determine that the user is performing a pat.

According to this embodiment, the touch information is compared with the first threshold, second threshold, third threshold, and fourth threshold, so that it is determined whether the current touch operation is a caress or a pat, thereby improving the accuracy of determining the current touch operation, and improving the flexibility of controlling the holographic projection device.

In an exemplary implementation, the determining, by the holographic projection device, that the touch operation is the caress performed on the holographic projection-based virtual role includes the following steps.

In a first step, the holographic projection device obtains a first position at which the touch point stays on the touch panel at a first moment and a second position at which the touch point stays on the touch panel at a second moment, a time interval between the first moment and the second moment being a frame period.

In a second step, the holographic projection device recognizes, in a case that it is determined that a distance between the first position and the second position is greater than the second threshold, an action in which the touch point moves from the first position to the second position as the swipe, and adds one to the quantity of swipes.

In a third step, the holographic projection device determines that the touch operation is a caress performed on the holographic projection-based virtual role in a case that it is determined that the quantity of swipes is greater than the first threshold.

The description of a case that the palm touches the touch screen is provided with reference to FIG. 5. A touch panel is in a to-be-detected state (S502). In this case, the palm touches the touch panel. It is determined by S504 whether a quantity of touch points is greater than 3, and in a case that the quantity of touch points is greater than 3, the coordinates of the touch points are recorded by S506. In this case, the coordinates of one of the touch points may be chosen, or the coordinates of all the touch points may be recorded. In a case that the touch points disappear, it is determined by S508 whether a quantity of the touch points is greater than 3 before the touch points disappear, and in a case that the quantity of the touch points is greater than 3, the disappearance coordinates of the touch points are recorded by S510. In this case, a touch point whose start coordinates are recorded may be chosen and the disappearance coordinates of the touch point are recorded, or the disappearance coordinates of all the touch points may be recorded. Start coordinates and disappearance coordinates of each touch point correspond to each other. A distance D between the start coordinates and the disappearance coordinates of a touch point is calculated by S512, and it is determined by S514 whether D is greater than the second threshold. In a case that D is greater than the second threshold, 1 is added to a quantity E of swipes by S516. It is determined by S518 whether E is greater than the first threshold, and in a case that E is greater than the first threshold, it is determined that a currently performed action is a caress. In this process, in a case that the quantity of the touch points in S504 and S508 is not greater than 3 or after it is determined that the current action is a caress, S522 is performed, and E is reset to 0. In a case of determining whether the quantity of the touch points is greater than 3, 3 may be set flexibly. In addition, the foregoing process is a process of determining whether the palm is performing a caress. In a case of determining whether the finger (or other parts) is performing a caress, the method may include, but is not limited to, deleting steps of S504 and S508 in the process in FIG. 5, and it is not necessary to determine whether the quantity of the touch points is greater than 3. It may be determined whether a current operation is the caress by using the remaining steps in FIG. 5.

According to this embodiment, it is determined whether the current operation is a caress by using the foregoing method, thereby improving the accuracy of determining the current touch operation, and improving the flexibility of controlling the holographic projection device.

In an exemplary implementation, the determining, by the holographic projection device, that the touch operation is the pat performed on the holographic projection-based virtual role includes the following steps.

In a first step, the holographic projection device obtains a third position at which the touch point stays on the touch panel at a third moment and a fourth position at which the touch point stays on the touch panel at a fourth moment.

In a second step, the holographic projection device determines, in a case that it is determined that a distance between the third position and the fourth position is less than the third threshold and a time interval between the third moment and the fourth moment is less than the fourth threshold, that the touch operation is the pat performed on the holographic projection-based virtual role.

For example, the description is provided below with reference to FIG. 6. For example, the touch operation is an operation performed on the touch panel by the palm. The touch panel is in a to-be-detected state (S602). After the palm touches the touch panel, it is determined by S604 whether a quantity of touch points is greater than 3, and in a case that the quantity of touch points is greater than 3, the coordinates and generation moment of one touch point or all the touch points are recorded by S606. It is determined by S608 whether the quantity of the touch points is equal to 0, and in a case that the quantity of the touch points is equal to 0, the disappearance coordinates and disappearance moment of the one touch point or all the touch points are recorded. A distance L between the coordinates of the touch point and a time interval T between a generation moment and a disappearance moment of the touch point are calculated by S610. It is determined by S612 whether L is less than the third threshold, and it is determined by S614 whether T is less than the fourth threshold. In a case that L is less than the third threshold and T is less than the fourth threshold, it is determined by S616 that the current operation is a pat. In a case that L is greater than or equal to the third threshold, or T is greater than or equal to the fourth threshold, or it is determined that the current operation is a pat, the touch panel enters the to-be-detected state in S602 again. In addition, in a case that the touch point does not disappear, the position of the touch point and a current moment are periodically recorded.

According to this embodiment, it is determined whether the current operation is a pat by using the foregoing method, thereby improving the accuracy of determining the current touch operation, and improving the flexibility of controlling the holographic projection device.

In an exemplary implementation, the obtaining, by the holographic projection device, a fourth position at which the touch point stays on the touch panel at a fourth moment includes the following steps:

In a first step, the holographic projection device performs the following steps in each frame period after the third position at which the touch point stays on the touch panel is obtained, until it is detected that the touch operation is ended:

In a second step, the holographic projection device obtains a current position at which the touch point stays on the touch panel at a target moment in a current frame period, a time interval between the third moment and the target moment being N frame periods, N≥1, N being an integer.

In a third step, the holographic projection device obtains, in a case that it is detected that the touch operation is not ended, a target position at which the touch point stays on the touch panel at the target moment in a next frame period of the current frame period, uses the target moment in the next frame period as the target moment in the current frame period, and uses the target position at which the touch point stays in the next frame period as the current position.

In a fourth step, the holographic projection device uses, in a case that it is detected that the touch operation is ended, the target moment in the current frame period as the fourth moment, and uses the current position as the fourth position.

In a fifth step, it is determined that the touch operation is ended in a case that an action region of the touch point on the touch panel is less than a fifth threshold.

For example, an example in which the finger touches the touch panel is still used for description. In a case that the finger touches the touch panel, a current position and a current time of the touch point are obtained. In a case that the touch operation is not ended, a touch position and a touch time of the touch point of the next frame period are obtained until the touch operation is ended, and a touch position and a touch time at a moment before the end are obtained. The touch position at the moment before the touch operation is ended is determined as the fourth position, and the touch time at the moment before the touch operation is ended is determined as a fourth moment. Because an area of the touch point between the finger and the touch panel increases as finger pressure increases, in a case that the area of the touch point is reduced to an empirical value, it indicates that the touch operation is ended and the finger leaves the touch panel.

According to this embodiment, the fourth moment and the fourth position are determined by using the foregoing method, thereby improving the accuracy of determining the fourth moment and the fourth position. The flexibility of controlling the holographic projection device is further improved.

In an exemplary implementation, after the recognizing the touch operation according to the touch information, the method further includes the following steps.

In a first step, the holographic projection device obtains an action region of the interaction between the touch point and the touch panel.

In a second step, the holographic projection device determines, according to a position of the action region on the touch panel, interactive information requested by the interaction request.

For example, as shown in FIG. 7, the touch panel is divided into six regions, A, B, C, D, E, and F, and the interaction generated in different regions correspond to different interactive information.

In some embodiments, after the touch panel is divided into different regions, the sizes and shapes of the regions may be the same or different, and a quantity of the divided regions may be any positive number greater than or equal to 1.

According to this embodiment, the interactive information is determined according to the position of the action region of the interaction between the touch point and the touch panel on the touch panel, thereby improving the flexibility of controlling the holographic projection device.

In an exemplary implementation, the determining, by the holographic projection device according to a position of the action region on the touch panel, interactive information requested by the interaction request includes either or both of the following two steps:

(1) The holographic projection device determines, according to the position of the action region on the touch panel, a role part of the interaction with the holographic projection-based virtual role; and determines, according to the role part, the interactive information requested by the interaction request.

(2) The holographic projection device determines, according to the position of the action region on the touch panel, an interaction type of the interaction with the holographic projection-based virtual role; and determines, according to the interaction type, the interactive information requested by the interaction request.

The interaction type may include, but is not limited to, an interaction form or an interaction mode. The interaction form may include, but is not limited to, an action performed by the role or a played sound, and the interaction mode may include, but is not limited to, a current mode of the role.

The mode may include, but is not limited to, a plurality of modes of imitating human emotions, for example, a shy mode, an upset mode, a scared mode, and a cute mode.

For example, as shown in FIG. 8, the touch panel is divided into six parts, and the parts respectively correspond to the head, the left arm, the right arm, the stomach, the left leg, and the right leg. Touching different regions indicates interacting with different body parts of the role, for example, patting the head or caressing the stomach. Alternatively, reference is made to FIG. 9 and FIG. 10. In FIG. 9, different positions of the touch panel are set to perform different interaction forms, such as dancing or singing). Moreover, in FIG. 10, different positions of the touch panel are set as different modes of imitating human emotions, such as a shy mode and a cute mode).

According to this embodiment, according to different positions of the action region on the touch panel, a role part or an interaction type of the interaction with the holographic projection-based virtual role is determined, thereby improving the flexibility of controlling the holographic projection device.

In an exemplary implementation, the controlling, by the holographic projection device, the holographic projection-based virtual role to perform an interactive action matching the interaction request includes at least one of the following steps:

(1) The holographic projection device controls the holographic projection-based virtual role to play an animation matching the interaction request.

(2) The holographic projection device controls the holographic projection-based virtual role to play audio matching the interaction request.

The controlling the holographic projection-based virtual role to play audio may include, but is not limited to, controlling the mouth of the holographic projection-based virtual role to change and simultaneously playing the audio by using a sound playing apparatus.

For example, after the holographic projection-based virtual role is projected, the holographic projection-based virtual role may be controlled to dance and perform an action, or the mouth of the holographic projection-based virtual role may be controlled to change, and audio is simultaneously played, to simulate that the holographic projection-based virtual role is making a sound.

According to this embodiment, the holographic projection-based virtual role is controlled to play the animation or play the audio, thereby improving the flexibility of the holographic projection-based virtual role.

In an exemplary implementation, the interactive control method further includes adjusting, by the holographic projection device, a mood parameter of the holographic projection-based virtual role; and controlling, by the holographic projection device, a role response mode of the holographic projection-based virtual role in a case that it is determined that the mood parameter reaches a target value, and/or, enabling, by the holographic projection device, a hidden skill of the holographic projection-based virtual role in a virtual scene.

The mood parameter may be indicated by using a number or in a form such as a quantity of red hearts or an energy value. The hidden skill may include, but is not limited to, a new animation, a new sound or a new phase. For example, the hidden skill is a new animation. After the mood parameter reaches a particular value, the role may be allowed to play the new animation. In a case that the mood parameter does not reach a particular value, the role is not allowed to play the new animation.

For example, the quantity of red hearts is used for indicating the mood parameter. After interaction with the holographic projection-based virtual role, the quantity of red hearts reaches a particular value. In this case, the holographic projection-based virtual role may make a new change. For example, the holographic projection-based virtual role may dance, sing, change clothes or the like.

According to this embodiment, it is determined according to the value of the mood parameter, whether to enable the hidden skill of the holographic projection-based virtual role, thereby improving the flexibility of controlling the holographic projection device.
